Spaceboy was one of several 'special' children born randomly from mothers who had shown no signs of pregnancy. He (along with six others) was raised by Reginald Hargreeves to save the world.
Spaceboy was created by Gerard Way and Gabriel Bá. Before publication and in the developmental process Spaceboy appeared dramatically different from his final pre development look and appearance. Gerard Way's focal point as far as the characters design revolved around Darwin and evolution. Potentiakl names for the character included Dr Darwin, Evolution Ear and Evolucius. His Gorilla body was also a lot more rugged and animalistic. Spaceboy's first appearance is in The Umbrella Academy / Pantheon City / Zero Killer #1.
Major Story Arcs
Luthor Hargreeves, 00.01, Spaceboy, is the leader of the Umbrella Academy. He was one of seven children adopted by Reginald Hargreeves, forming the Umbrella Academy. Spaceboy is also the twin brother of 00.05.
On the Umbrella Academy's first mission, Spaceboy prevents the rogue Eiffel Tower from killing the rest of the team. He also figures out that the mastermind behind its insanity was Robot Zombie Gustav Eiffel. Kraken accidentally destroys the control panel, and the Eiffel Tower launches into space. While the rest of the team enjoys ice cream, Spaceboy tells Reginald Hargreeves that some day he wants to go into space. Hargreeves confidently tells him that he will.
Spaceboy accomplishes his dream early. He travels into space with Pogo. He is in an accident, and Reginald Hargreeves saves him by attaching his head to a Martian gorilla body. Spaceboy returns to space, and sets up a moonbase with his trusty robot.
He is shocked when he hears the new of Reginal Hargreeves' death, and returns to Earth for the funeral. Not having kept up with the state of the rest of the Academy, he is surprised by the news that Rumor is divorced. After the funeral, things quickly turn nasty between Spaceboy and Kraken. Spaceboy is preparing to finish him off when his attention is diverted by the flames of the burning carnival in the distance. Spaceboy recalls Dr. Terminal's robots that were programmed to attack when the Umbrella Academy reformed. Spaceboy, Rumor, and Séance head to the carnival to stop the robots. Kraken goes as well, but away from the others.
Spaceboy quickly takes control, and destroys the robots. He watches as Kraken verbally abuses Vanya, sending her running to the Orchestra Verdammten.
Back at the base, Spaceboy kisses Rumor on the rooftop. They are interrupted when Vanya, now the White Violin, attacks the base and kills Pogo, before retreating to the Icarus Theater.
Spaceboy, Rumor, and 00.05 go to stop Vanya, while Séance readies himself for his part of the plan. White Violin slits Rumor's throat, and Spaceboy abandons the others to take Rumor to the hospital. The others stop the White Violin and save the world. Spaceboy and Kraken temporarily reconcile.
A few weeks later, Spaceboy only eats junk and watches television, occasionally arguing viciously with Kraken. He is only snapped out of his stupor by Séance's frantic plea over the television wavelengths. Spaceboy runs to where Séance has been captured by Hazel and Cha-Cha, but he is too late. They have already shot Séance in the head. They taze Spaceboy, shorting out his circuitry. Séance returns from beyond the grave, and possesses Hazel, shooting Cha-Cha and Hazel in the head. He then returns to his body and reboots Spaceboy.
While he was comatose, Spaceboy dreams about having a normal life. He is married to Rumor, and has two mutated chimpanzee children. Séance is dead, and being served for dinner. Then everything explodes, and Reginald Hargreeves tells Spaceboy nothing will ever be normal.
Spaceboy returns to consciousness, and goes with Séance and Kraken to stop 00.05 from murdering John F. Kennedy. Séance, not really knowing how to work the chronometer, sends them 3 years too early. Spaceboy, needing to do some soul-searching, retreats into the jungle. When the time is right, he meets up with the others, but is too late to stop Rumor from killing Kennedy. When Rumor tells him that she did it to prevent them from killing him before he was born, Spaceboy is furious. Once they are back in their time, he goes back to the jungle.
Powers and Abilities
Spaceboy has super-strength, heightened by his gorilla body. His life-support system is also a jet-pack, and he is good with a laser-pistol.
Spaceboy appears in the Netflix live action adaptation of the Umbrella Academy with his real name as Luther Hargreeves. Rather than having his head transplanted onto the body of a gorilla, he is given a life saving serum that gives him a simian appearance as a side effect.
Like the rest of the Umbrella Academy, Luther was born on 1st October, 1989 to a woman who showed no previous sign of pregnancy and adopted by the billionaire inventor Sir Reginald Hargreeves to be trained to save the world. Raised by their robot mother figure Grace and brutally trained to be superheroes from youth, Luther passionately embraced his duties as the team leader and being designated Number One due to his superhuman strength and durability.
Luther was the only one who stayed behind after everybody left, painfully remaining loyal to his father figure, which made him lonely and depressed. A solo mission to stop a biochemical threat left Luther critically injured and had a serum used on him to save his life which left him with an ape like physiology. To help his focus, Reginald assigned him to the Moon to be on the lookout for extraterrestrial threats, which left him further lonely and depressed and feeling alienated due to his new appearance.
After learning of his father's death, he returns to Earth to attend the funeral, where he's antagonized by Diego, including fighting with him at the funeral, and also had difficulties adjusting to being reunited with his adoptive siblings and assumes his father was murdered and leads his family in an investigation. But Luthor's own confidence in himself is shattered when he discovers that none of his reports from his time on the Moon was heeded by his father and he was sent away to be out of his father's way which severely crippled his own self esteem.
His father's death also regrew his connection with Allison in light of his disillusion with his mission, where they end up kissing after a dance, after which he accepts to meet his adoptive nephew. In the new timeline, he enters into hedonism and debauchery to cope with his shattered identity, Klaus finds him in his time of need. Afterwards, they uncover Vanya to be the apocalypse's source due to her previously unknown powers which made her the strongest superhuman in their ranks. Their differing views on containing her or reasoning with her led to Vanya being trapped in her old confinement chamber and unleashing her powers.
Now fully transformed into the White Violin, she began destroying their family mansion, which was Luther's fault due to not trusting her. But with Five's aid, they avoided perishing in the apocalypse and was stranded in the 1960s by Five's lack of control over his powers. Luther finds himself transported to Dallas, where he builds up a life working for the gangster Jack Ruby. He fights regularly for him in an underground boxing-ring, and takes to the man as a mentor and replacement father figure. Luther quickly becomes dissatisfied with his life, however, when he bumps into Vanya. He apologizes to her eventually while beginning to search for Allison, where he uncovers the life she built without him. He reunites with Five, but doesn't enter his plan due to feeling shrunk in significance over his role in his previous occupation and the way the family was damaged. He eventually talks with Allison over their new lives, becoming persuaded to join the fray once more to stop the apocalypse which was due to their actions with Five's aid. They manage to restore the timeline, despite facing new and old enemies in the Swedes and the Handler, who brought the entire Commission to destroy them. They managed to return to 2019, where he uncovers a new version of the Academy as the Sparrow Academy, where he's no longer Number One.
